Abstract: BACKGROUND: Systematic repetition postures adopted during trainings
could generate alterations in the sagittal spinal curvatures. OBJECTIVE: The purposes were: 1) to analyse the sagittal spinal
curvatures and pelvic tilt in Latin American style dancers; 2) to compare
the spinal sagittal mobility and hamstring muscle extensibility between
Latin American style dancers and non-dancers; and 3) to evaluate the
influence of wearing dance shoes upon the sagittal spine posture in
standing. METHODS: A total of 20 Latin American style professional dancers
and 20 non-dancers (control group) were evaluated during standing, relaxed
sitting, maximal trunk flexion with knees flexed and extended, lying prone,
and maximal trunk extension. Additionally, dancers were analysed while
standing barefoot, and wearing heeled-shoes, during forward walking and the
paso-doble posture. The hamstring muscle extensibility was evaluated by the
active knee extension test. RESULTS: The spinal morphology in Latin American style professional
dancers is characterised by lower thoracic kyphosis, lumbar lordosis and
anterior pelvic tilt in the standing posture as well as a flexible spine,
especially in flexion postures, in addition to suitable hamstring muscle
extensibility. CONCLUSIONS: The spinal morphology of Latin American style
professional dancers is characterised by lower thoracic kyphosis and lumbar
lordosis and anterior pelvic tilt in the standing posture as well as a
flexible spine, especially in flexion postures, and suitable hamstring
muscle extensibility.
